"value": "A String", # The phrase itself. We recommend using a binary search approach to finding the optimal value for your use case as well as adding phrases both with and without boost to your requests.

Though `boost` can accept a wide range of positive values, most use cases are best served with values between 0 and 20. The higher the boost, the higher the chance of false positive recognition as well. Positive value will increase the probability that a specific phrase will be recognized over other similar sounding phrases. Overrides the boost set at the phrase set level. To specify a region, use a () with matching `us` or `eu` location value. If you are calling the `` endpoint, use the `global` location. Speech-to-Text supports three locations: `global`, `us` (US North America), and `eu` (Europe). For more information on asynchronous speech recognition, see the (). Returns either an `Operation.error` or an `Operation.response` which contains a `LongRunningRecognizeResponse` message. Longrunningrecognize(body=None, x_xgafv=None) Performs asynchronous speech recognition: receive results via the interface.
